SDS-PAGE of seed proteins and SEM of seed coat surface in Caesalpinia gilliesii Wall., C. pulcherrima Sw., C. sepiaria Roxb. and Delonix regia Raf. (Leguminosae - Caesalpinioideae)

Abstract

SDS-PAGE of seed protein profiles , SEM of seed coat surface patterns and selected macromorphological characters were studied in the related taxa Caesalpinia gilliesii, C. pulcherrima, C. sepiaria and Delonix regia. The obtained characters were used as one set of data and analyzed using the NTSYS-pc program. The dendrogram produced showed a closer relationship between D. regia & C. pulcherrima. Taxonomic relationships between the four taxa were discussed in the light of their morphological, anatomical, embryological and phytochemical criteria. Merging of C. pulcherrima in the genus Delonix has been suggested.
